  Jerusalem shall be like an altar,
  where blood is poured out
  like this name of Ariel.” (Source: Kupsabiny Back Translation)
• Newari: “But I will surround Ariel
  and she will cry and mourn
  and she will be like burning fire in alert.” (Source: Newari Back Translation)
• Hiligaynon: “But I will-attack her, and her residents will-cry and will-lament. And for me, the whole city will-be like an altar which is soaked with blood.” (Source: Hiligaynon Back Translation)
• English: “But I will cause you to experience a great disaster,
  and when that happens,
  people will weep and lament very much.
  Your city will become like an altar to me
  where people are burned as sacrifices.” (Source: Translation for Translators)
